Efficacy of core vitrectomy preceding triple corneal procedure

Area of Science:

• Ophthalmology
• Corneal Surgery
• Cataract Surgery

Background:

• Triple corneal procedures combine penetrating keratoplasty, extracapsular cataract extraction, and intraocular lens (IOL) implantation.
• The necessity of core vitrectomy before these procedures is debated, particularly regarding vitreous pressure management.

Purpose of the Study:

• To assess the effectiveness of performing core vitrectomy prior to a triple corneal procedure.
• To compare outcomes between patients who underwent vitrectomy and those who did not.

Main Methods:

• A randomized controlled trial involving 31 eyes of 31 patients indicated for triple corneal procedures.
• Patients were assigned to either a triple procedure with core vitrectomy or a control group without vitrectomy.
• Key outcomes included IOL implantation success, positioning, complications, endothelial cell loss, and best corrected visual acuity (BCVA) over a six-month follow-up.

Main Results:

• No statistically significant differences were observed in most clinical parameters between the groups.
• A trend suggested that core vitrectomy may facilitate IOL implantation (p = 0.11).
• Vitreous loss occurred in two control group cases; no retinal detachments were reported. Higher vitreous pressure correlated with body mass index and age.

Conclusions:

• Core vitrectomy is not universally required before triple corneal procedures.
• The decision to perform core vitrectomy should be individualized based on patient factors and potential risks like vitreous loss.
